The English Opening is the chess opening 1.c4 (in algebraic notation), the fourth most popular opening move in chess. White hopes to control the center by first gaining support on the side. Common responses for Black are 1...e5 (which can lead to positions similar to the Sicilian Defense but with opposite colors), 1...c5 or 1...Nf6. White has the option of opening the game early with d4, or to prepare with a fianchetto of the king´s bishop (g3 and Bg2).

If White does play d4, then the English can transpose into either the Queen´s Gambit or an Indian Defense.

Although there are many lines of the English with a distinct character, it also frequently transposes into other openings. For example, after

1.c4 Nf6 2.Nc3 g6 3.d4 d5

the game has transposed into the Grünfeld Defence, usually reached by the move order
